Precautions for commissioning and maintenance of gas burner during low nitrogen transformation of boiler:

1. In case of continuous failure of secondary ignition procedure of gas burner, shut down the burner to check whether the gas supply system of burner is normal and whether the circuit wiring is correct. Restart the burner after removing the fault;

2. It is forbidden to knock or rub the gas supply pipeline with a wrench or metal rod to avoid static electricity or spark and gas explosion;

3. Smoking, welding, cutting and other illegal operations are strictly prohibited at the gas supply valve group or pipeline flange surface;

4. It is strictly prohibited to conduct any open fire test near the pipeline, valve group and pressure regulating valve to avoid major accidents;

5. In the air supply pipeline, it has been emptied, but there are residual gas or droplets on the pipe wall. In case of, electrostatic spark and open fire, it will also cause combustion and explosion;

6. When the valve group needs to be disassembled in case of failure, the main valve at the front end of the valve group must be cut off first, and then the gas in the pipeline from the main valve to the valve group shall be vented, and then the valve group can be disassembled and repaired;

7. It is forbidden to use non explosion-proof electric tools on site;

8. Before using the leak detection device, the valve group must be checked;

9. Before starting the combustion engine, the air supply pressure test must be carried out to check whether there is leakage. After confirming that it is normal, the simulation operation can be carried out;

10. When the burner is not in use, inform the customer to cut off the main air supply valve and main power supply switch;

11. It is not recommended to debug the burner at night;

12. At the end of commissioning, operators shall be organized to train them in the use and operation direction, and the operation process shall be established if necessary.
